Title:
FLOW CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2022/242494
Kind Code:
A1
Abstract:
Provided is a flow control valve (1). The flow control valve (1) comprises: a valve body (2), which is provided with a valve hole (21), a guide hole (22) and a lateral hole (23) that are in communication with each other; and a valve core (3), which is located in the guide hole (22), and can move in an axial direction of the guide hole (22) to control the opening and closing of the valve hole (21), thereby allowing or blocking the flowing of a fluid between the valve hole (21) and the lateral hole (23). The lateral hole (23) is internally provided with a connecting portion (231) connected to the valve hole (21), and the connecting portion (231) has a borehole surface (232) bored around an axis of the valve hole (21). The valve body (2) of the flow control valve (1) is provided with the lateral hole (23) and the borehole surface (232) located in the lateral hole (23), and the borehole surface (232) is located at a joint between the lateral hole (23) and the valve hole (21) and is arranged around the axis of the valve hole (21). By means of the lateral bore (23) and the borehole surface (232), the valve core (3) of the flow control valve (1) has as little lateral force as possible when a fluid flows between the valve hole (21) and the lateral hole (23).
